Pacific Toxicology Laboratories

What Pacific Toxicology Laboratories does

Pacific Toxicology Laboratories is a privately held, for-profit analytical testing laboratory founded in 1984 and headquartered in Chatsworth, California. The firm provides drug testing, biological monitoring, medical surveillance, drug monitoring, and forensic toxicology services, serving customers who require regulated specimen analysis — typically employers, treatment programs, legal/forensic clients, and occupational health programs. The business operates with 11-50 employees and is led by founder and CEO Jeff Lanzolatta, supported by an executive team that includes a Chief Operating Officer (Ali Mikhchi), a Chief External Operations Officer (Sue Barbosa), a Chief Financial Officer (Neil Patel), and a VP of Marketing and Compliance (Rana Ostadrahimi). The structure suggests a small, operator-led specialty lab focused on regulated toxicology workflows rather than high-volume commodity testing.

The firm's underlying technology platform, instrumentation stack, pricing model, distribution channels, and specific customer mix are not disclosed in the available input — the corporate website (pactox.com) returned only a security verification page with no substantive company content during the data collection pass. As a result, technical differentiation, contract economics, and revenue mechanics cannot be characterized beyond the general category description. The presence of dedicated compliance and external-operations leadership indicates that regulatory adherence and client relationship management are treated as core operational competencies rather than commoditized back-office functions, which is consistent with the firm's positioning in a tightly regulated testing category.

Commercially, there is no disclosed information on funding history, ownership structure, M&A activity, product launches, geographic footprint beyond the Chatsworth headquarters, customer logos, or pricing models. No AI/ML capabilities, patents, certifications, awards, or partnership arrangements are documented in the input. Accordingly, the analytical picture is limited to firmographic facts: a 40-year-old, small, founder-led specialty toxicology lab with a formalized C-suite, whose commercial scale, growth direction, and competitive positioning cannot be quantified from the evidence provided.
